IMPROVEMENT IN PIN-FASTENINGS FOR JEWEL-RY.

Specification forming part of Leiters Iaicnt No. 143,223, dated March 3, 1874; application 'led June i4, 1873.

To all whom it Imay concern:

Be it known that we, ABRAHAM LvoNs and ISAAC B. ABRAHAMS. of New York city, in the county of New York and State of New York, have invented a new and valuable Improvement in Pin-Hinges for Jewelry or J ewelers Pins; and we do hereby decla-re that the following is a full, clear, and eXact description of the construction and operation ofthe same, reference being had to the an nexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of our wire pin. Fig. 2 is a View of the post. Fig. 3 is a view of the hook. Fig. 4 is a view ot' the post and pin. Fig. 5 is a top view of the post. Fig. 6 is a modification.

Our invention relates to jewelry-pins; and it consists of a new construction and arrangement of the pin, its pivot-post, and mode of pivoting' and of the catch.

The object of our invention is to avoid the labor of making' and inserting pivot-pins and of drilling the holes for the same, and to avoid soldering the post and the hook together of several pieces by ina-kin g the said parts out of one solid piece and shaping the same between swages or dies.

In the drawings, A represents a wire pin, such as is used yfor fastening brooches, scarfpins, &c., to wearing apparel. The said pin is pointed at one end and bent into S shape at the other end. B represents a post made of one solid piece of metal with a foot, b, provided with screw-threads, and a forked head, b1,

provided with a hole, b2. C represents a pinhook, consisting of a foot, c, provided with screw-threads and a hook, c. rlhe post B and the hook C are screwed into tapped holes on the jewelry, for which they are intended. The

pointed end of the pin A is then inserted into the hole b2 until it arrives at the second or return crook, when the straight part is turned up. The pin is secured to the post by getting the straight part into the fork of the head b1 and bending the second crook so together, that it almost closes around the metal between the hole b2 and the fork-slot in the head bl, which serves instead of a pivot-pin. The jew-v elry-pin is now in working order.

The old method of manufacturing the posts is very laborious, as the post and the hook are made up of wire tubes and plates soldered together and filed into shape, drilled, and pro vided with a pivot-pin by hand-work. The posts are now by my method shaped between dies or swages with one blow or one single turn of a screw on a screw-press. The hook C, which only has a thick shank and is thin above, is made of wire, which is upset to the thickness of the shank b at one end, leaving the other end undisturbed for the hook. The upsetting is done by machinery and between dies, or by hand with swages, and it requires very little time to do'the amount usual in a days work (by the old method of soldering wires together) to get the right thickness of metal.

rlhe above-described return crook may be substituted by a pin or rivet head, b3, which is attached in the same manner and operated the same as the pin with the return bend.

What We claim as new, and desire to secure by Letters Patent, is

l. The pin A, in combination with the post B and the hook C, when said parts are constructed substantially as specified.

2. In a jewelry-pin, the post B, composed of the threaded shank b, the forked head bl, and

the hole b2, substantially as specified.

3. In a jewelry-pin, the hook C, with the upset and threaded shank c and the hook c', substantially as specified. l

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
